Unstable wireless on Minix UH-9?

Hi folks,

I’ve got a Minix UH-9 that I’d like to move from cabled connection to wifi. This thing is supposed to support AC networks, which should work great. My main wifi network supports both 5ghz and 2.4ghz clients.

Added the wifi network, try to get it online - half the time it fails with a ‘failure’. Why exactly is not mentioned. When it does get online, the speeds are abysmal until it fails over to the 2.4ghz band, where it is ‘acceptable’, but nothing more than that. Pings take up to 24 seconds from time to time (not ms)… is there anywhere anything I can see/check to figure out why this is so abysmal? Or is the wifi on the UH-9 just bad?

Edit: I plugged in a random 2.4ghz wifi plug I had lying about, and it works so much better. This thing doesn’t even have an antenna to speak of.

Is there anything I can try to get the built-in wifi to work decently?

on some boxes there is a mod to move the internal aerial, but I googled & couldn’t find anything.

Mine actually has a nice external antenna - I would have guessed it would use it, but well…
